Container and liquid-tight liner therefor



June 23, 1936. G. v. HAVEN CONTAINER AND LIQUID TIGHT LINER THEREFOR Filed May 4, 1935 m V h j M. FNWMM 071 m Patented June 2 3, 1936 UNITED STATES PATENT OFFICE CONTAINER AND LIQUID-TIGHT LINER THEREFOR 1 Claim.

My invention has for its object the provision of a simple and highly efficient container having a removable water-tight paper liner for general use in carrying liquid.

While the invention is intended for general use, it is especially well adapted for use as a camp pail.

The container, when not filled with a liquid, is fiat.

and can be carried in a very small space which is highly important when transporting camp equipment in an automobile, canoe or other vehicle, or when making portages. The liner for the container is formed to fit the container by folding a square piece of waterproof paper when needed, and as will hereinafter appear. Waterproof paper from which the liners are folded is of the proper size and can also be carried in compact form.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

In the accompanying drawing, which illustrates the invention, like characters indicate like parts throughout the several views.

Referring to the drawing:

Figs. 1 to 4, inclusive, are perspective views showing successive steps in the process of forming the liner, the completed liner being shown in Fig. 4;

Fig. 5 is a perspective view of the container and liner with the sides thereof separated as they will appear when the liner is filled with a liquid, as shown in Fig. 6; and

Fig. 6 is a view in vertical section taken on the line 6-6 of Fig. 5.

Referring first in detail to the container which comprises two duplicate side pieces I cut from canvas or other suitable fabric and placed, the one piece upon the other. The top and bottom edges of the side pieces I are parallel and the upright edges thereof are in upwardly diverging relation. These side pieces I are connected at their bottom and upright edges by stitches 8 and the top edge portion thereof is folded outwardly and downwardly upon itself to form a hem 9 secured in place by stitches I 0. Each side piece I is provided with a loop-like handle II, the end por-'- tions of which are tucked under the hem 9 and securedto said hem and the side pieces I by stitches l2. When the container 1 is not in use its side pieces lie flat, the one upon the other. If necessary when packing the container, the same may be folded or rolled in order to place the same into a more compact space.

Referring now in detail to the liner I 3 of the container, the same is formed from a single square piece of waterproof paper. The size of the square piece of paper is such that when folded to form the liner, said liner snugly fits in the container and is removably held thereby.

The process of folding the improved liner is as follows: The square piece of paper is first folded upon itself with one corner on the diagonally opposite corner to form a right angle triangle and the paper creased at [4 or, in other words, at the hypothenuse of said triangle, see Fig. 1.

Next, the lower right hand corner section l5 of the triangle I4 is folded upon said triangle in a position in which its point is at the left hand edge of the triangle l4 and with its upper edge parallel to the hypothenuse of the triangle and the paper again creased at It, as shown in Fig. 2. Next, the partially formed liner is turned over and the lower right hand corner section I! of the triangle M is folded upon said triangle on the opposite side thereof from the corner section l5 and with its upper edge aligned with the upper edge of the corner section l5, see Fig. 3,. The paper is again creased at l8. Next, the uppermost pointed section of the triangle M is folded outwardly and downwardly onto the corner section l1 and creased over the upper edge of said section l1. Finally, the partially formed liner is turned over and the other upper pointed portion of the triangle I4 is folded outwardly and downwardly onto the corner section l5 to complete the liner, as shown in Fig. 4.

The completed liner is now ready to be placed in the container which not only affords a reinforcement therefor but affords convenient means for carrying the same. The liner may be made from relatively light-weight paper for the reason that the container will hold said liner against undue pressure from liquid in said liner.

Due to the dilficulty of keeping a water pail in a clean and sanitary condition when in camp, the above described container and liner will fill a long-felt want for the reason that the liner can be thrown away when the same is empty and a new liner folded and placed in the container, thus keeping the pail clean and in a sanitary condition.

It will of course be understood that the liners may be folded at the time of manufacture in place of folding the same when needed.

What I claim is: As a new article of manufacture, a container comprising two side pieces cut from fabric, placed the one upon the other and fastened together at i for the container formed by folding a single piece of paper, said liner being held folded by the container with freedom for like opening and closing movements therewith.
